T0-aZZ whom itmay-concern:

Be it knownthat I,PAUL KR0UT, a subject of the Kingzof Belgium, residing at 61 Wilton Road, London, England, have invented new and useful Improvements in or Relating to Illuminated Signs, of which the following-is a specification.

This invention relates to illuminated signs. Y

mA sign constructed according to this invention comprisesia rotatable member such as a frame or spider having lamps-mounted thereon-kind a translucent screen masking some or all ofthe'lam'ps, and means are provided for rotating some or all of the lamps on their own axes} J t The'frame' maybe located within a stationary case or mam-together with one or more-.trans lucent screens-, constitute a casing-"or enclosure. -In-th'e latter" case there may be providedone or more externalelectric' lamps-or globes of transparent material which rotate with the frame. The said electric lamps or globes may also if desired be made to rotate upon their own axes. The said internal and/or external-electric lamps or globes may be painted or stained in various colour designs, or be provided with coloured glass, so as to change the colours of the visible portions in succession. The said visible portion of the external electric lamps or globes of this apparatus may be enveloped by secondary globes of transparent material or opal glass which may also or alternatively be painted or stained in various colour designs and also show the visible portions in alternate succession. The en velopo or secondary globes may remain sta tionary or may be made to rotate also upon their own axes at a slower or faster speed than the primary electric lamps or globes so as to multiply the variation in colours. The motion of the envelopes or secondary globes may be obtained by the same mechanism which actuates the primary electric lamps or globes. The internal and external electric lamps or globes may be automatically switched on and ofi' simultaneously or alternately by the action of the said internal mechanism or by an external switching device. The timing of the said switching may be varied by adjustment. The whole of the apparatus may be driven by mechanical, electrical or any other means of power.

The construction of this sign may be so arranged that the said external electric covered with translucent material.

Preferably the stationary case comprises a pair of rings cast in one with a pair .of inverted U shaped supports which serve-to position the rings a distance apart from one another. The rings areprovided.,with a cross member carryin-gbearings forthe v,ro tating frame. Preferably theirings are also divided so that the lowerhalves; .can be lamps or globes are completely or partly dropped or turnedaboutaapivotito obtain access to the rotating'frame-orto replace the frosted screens. t

:The accompanyingdrawlngs -1llustrate ,apaaratus made in accordance with this mVention. Figure l isa front elevation {with one i of the screens removed-.1 .Flgure'. 21315845369 I .is a shaft f which passes through the frame a. and carries at its outer end an incandescent lamp g. On each shaft f is a bevel pinion h meshing with another bevel pinion j on the spider b and 7c is a scroll adapted to engage one of the teeth of the bevel pinions j as the frame a rotates thereby rotating the bevel pinions h a distance corresponding to one tooth. Mounted on two legs of the spider b are shafts Z each of which carries at one end an electric incandescent lamp m and at the other end a bevel pinion n in mesh with a bevel pinion 0 on a shaft f whereby the shafts Z and lamps m rotate as the shafts f rotate. The frame a is located between two screens p of frosted glass mounted in the case y, so that the lamps g are directly seen by the observer whilst the lamps m illuminate the screens [9. The hub 0 has upon it a worm wheel 9 which is driven by a worm 1.

Electric current is supplied to the lamps through leads 8 which extend from slip rings at to which current is supplied through brushes u thence to slip rings 1: connected to the lamps.

In the modification shown in Figures 6 and 7 the case 3 is formed of a pair of rings cast inone, with a pair of inverted-U shaped supports 3/ which serve to position the rings a distance apart from one another. The rings are divided and hinged at 1 so that the lower halves carrying the frosted screens can be swung down to obtain access.

to the rotating frame a or mechanism thereon or to replace the frosted screens p. The cross members 10 on which the spindle e is fixed am carried by the upper halves of the rings axes and lamps carried by th'e cross shafts.
